Hello, I have a problem with a plugin.
When I compile it it shows me this error: error 021: symbol already defined: "zp_get_user_level".
The code:

#include <amxmodx>
#include <fun>
#include <zombie_plague_special>
#include <zombiexp>

Could you please help me? thank you in advance.

The error means exactly what it means. Post the custom .inc files. The same symbol is defined in both of them.
